Breaking Down Barriers: Custom Protein Degraders

How Fluorochem Supports You

Targeted Protein Degradation (TPD) represent a revolutionary approach in chemical biology and drug discovery, enabling the selective moderation or removal of proteins, including those associated with diseases. Unlike traditional inhibitors, bifunctional degraders such as PROTACs (Proteolysis-Targeting Chimeras), AUTACs (Autophagy-Targeting Chimeras) and LyTACs (Lysosome-Targeting Chimeras) and actively induce protein elimination rather than merely blocking function. By simultaneously binding a target protein and the biological machinery involved in protein degradation pathways, the protein is ultimately destroyed by the body’s own processes. Molecular glues – small molecules that also induce protein-protein interactions – can be utilised in the same way, such as in the case of CELMoDs (Cereblon E3 Ligase Modulators).

The cellular degradation pathways these molecules trigger, include the ubiquitin-proteasome system (UPS), autophagy and the endo-lysosomal pathway. This approach can modulate protein levels with high specificity. Their applications extend across cancer research, neurodegenerative disease studies, and immune modulation, offering new therapeutic possibilities where traditional small molecules and biologics fall short.

Alongside an extensive catalogue of PROTAC building blocks, Fluorochem supports researchers by providing custom protein degrader synthesis, facilitating the development of these novel degradation strategies. With precise linker design, E3 ligase selection, and structural optimisation, these degraders open new frontiers in targeted protein regulation and drug development.
